using the IR, the 13C, and DEPT NMR spectra of your product
determine the identity of your unknown ester from a C-4 or C-5
alcohol. the identity of the C-4 or C-5 alcohol also needs to be
determined.
The following C-4 or C-5 alcohols will be used in this
experiment:
1-butanol (n-butyl alcohol)
2-butanol (sec-butyl alcohol)
2-methyl-1-propanol (isobutyl alcohol)
3-methyl-1-butanol (isopentyl alcohol)
1-pentanol (n-pentyl alcohol)

Explain why the
IR corresponds to a particular compound of those that are possible
based on BP and why it couldn't be any of the others -mention at
least 3 IR peaks that are present that correspond to functional
groups in your molecule, and discuss specific peaks that were
either present or absent that allowed you to rule out the other
compounds possible based on the boiling point. Reference your IR

Hi I just need a little help breaking down some information. I have an unknown, which i distilled on a microscale. The boiling point I got was 102 C. I performed a DNPH test which came back negative so its not an aldehyde or ketone, also a chromic acid was positive for a primary or secondary alcohol, and potassium permanganate negative for alkene or alkyne. My IR came back with 3 sp3 C-H peaks an O-H and C-O. The possible...
